The Germany international, most recently linked with Inter Milan and Liverpool, hinted last month that he may consider quitting the Westfalenstadion to "try something different".

Reus also confirmed that a number of sides have attempted to sign him in the past, but Zorc is optimistic that the 28-year-old - without any appearances under his belt since May - will still be around in his 30s as another new deal is a possibility.

"We see Marco at Dortmund in the long term," he told Kicker.

Zorc revealed in the same interview that Dortmund are happy with current goalkeeper Roman Burki, amid ongoing links with FC Koln's Timo Horn and Kevin Trapp of Paris Saint-Germain.
